JOHN E. HEMENWAY, OF NEW YORK, N. Y.

PRESSURE-ROLL RELEASE FOR CLOTHES-WRINGERS.

To all whom it may concern:

Be it known that I, JOHN F. HEMENWAY, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Pressure-Roll Releases for Clothes-Wringers, of which the following is a specification, reference being had therein to the accompanying drawing.

, This invention relates to certain new and useful improvements in pressure roll release for clothes wringers, the object being to provide a positive release which can be quickly operated in order to instantaneously release the pressure on the pressure rolls.

Another object of my inventionisto provide a pressure release which is exceedingly simple and cheap in construction," and one in which a resilient member is employed for holding the pressure means in predetermined position, operating means being provided in connection with said resilient retaining means adapted to move the resilient member into such position that the pressure means will be instantaneously released and held in that position until reset.

tion showing the application Another and further object of my invention is to provide a pressure release in which the movable pin is mounted within the top bar of'the wringer frame having a rack formed on the shank thereof adapted to be engaged by a pivoted pawl for holding the pin in ad usted position so as to maintain the resilient member in such position thatthle1 pressure will be released on the pressure r0 I Other and furtherobjects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the accompanying drawings,

Application filed July 26, 1916. Serial No. 111,405.

wringer frame 1 having slotted side bars in which are mounted superposed bearings carrying pressure rolls 2 and 3 which are of the ordinary construction now in use, the upper bearings being provided with spring supports on which are mounted pressure springs 4 which are engaged by plates 5 carried by a pressure bar 6, said plates being carried by a movably mounted top bar 8 mounted within the slotted portions of the side bars of the wringer frame.

Secured over the upper end portions of the side bars of the wringer frame are members 9 provided with substantially inverted T-sh'aped slots 10 into which are adapted to extend the end portions of a retaining spring '11 slidably mounted on the under face of the bar 8, said spring being provided with substantially T-shaped ends 12 coiiperating with the inverted T-shaped slots 10 in such a manner that when the ends of the spring are drawn inwardly, the stem of the T will be brought into vertical alinement with the reduced portions, or the stems of the inverted T-shaped slots 10, so as to allow the top bar 8 of the wringer frame to move vertically in order to release the pressure on the pressure rolls as will be hereinafter fully described.

The top bar 8 of the wringer frame is provided with a centrally disposed vertical bore 13 in which is mounted a headed pin 14, the shank of which is provided with a rack portion 15 adapted to be engaged by a spring actuated pawl 16 pivotally mounted on the top bar 8, the shape of the pawl and rack being such that the pin is free to move downwardly and is held in its adjusted position by the pawl. The lower end of the pin 14 is rounded and extends'below the top bar into the centrally disposed bowed portion 11 of the spring 11 so that when the pin 14 is forced downwardly, the ends of the spring 11 are drawn inwardly so as to bring the stem of the T-shaped heads thereof into alinement with the stems of the inverted T- shaped slots 10 of the members 9 which allows the top bar to move upwardly within the side bars of the wringer frame so as to release the pressure on the pressure rolls, the

upward movement being limited by the length of the slot in the member 9, and the top bar is prevented from becoming detached from the wringer frame by the heads of the spring.

The construction of pivoted pawl herein shown and described is formed of a blank having depending apertured cars 16 which straddle the top bar 8 and through which a pivotal pin 16 passes for pivotally mounting the pawl i n p osition.. upon the top bar,

said blank having a tail portion lti under which is arranged a spri'ng"l(3* which normally holds the pawl 16 in engagement with the rack 15 of the pin 14. so as to lock the pin in its adjusted position, the pin 14 being free to move downwardly as the pawl rides over the teeth ofthe rack but is prevented from moving upwardly until the tail 16 of the pawl is depressed so as to throw the pawl out of the path of travel of the pin which allows the pin to return to its normal position in order to place the top bar into such position ofthe wringer frame, that proper tension can be applied to the pressure rolls.

While I have shown and described the particular construction of operating'member in the form of a pin engaged by a pivoted pawl of a particular construction, I do not wish to limit myself to any particular construction of a slidably mounted operated member and pivoted pawl as various other constructions of operating members and pawls can be used without departing from the spirit of my invention, as the main object to be accomplished is to provide an operating member which can be forced downwardly into engagement with the retaining spring in order to draw the ends of the spring into such position that the top bar will be released, the spring being held in its adjusted position by the pin being locked by the pawl.

From the foregoing description it will be seen that I have provided a pressure release for a wringer in which a movably mounted top bar is mounted within the wringer frame and is provided with a slidably mounted spring having T-shaped ends cooperating with T-shaped slots formed in members secured to the side bars so as to hold the top bar in predetermined position within the wringer frame in such a manner that when the operating member which cooperates with the spring is depressed, the ends of the spring will be drawn inwardly so as to release the top bar and allow the same to move vertically within the wringer frame in order to release the pressure on the pressure rolls.
